San Diego Solar Incentives
Solar in San Diego is more affordable than most homeowners expect once you stack the incentives. The 30% federal tax credit, California's SGIP battery rebate, and NEM 3.0 net billing can cover a large share of your system cost and bring typical payback to roughly 6 to 10 years.
What you can claim in 2026
30%
Federal tax credit (ITC) on solar + battery, through 2032.
$6k–$8.4k
Typical ITC value on a $20k–$28k San Diego system.
SGIP
California rebate toward a home battery (Powerwall / Enphase).
6–10 yr
Typical payback once incentives are stacked.
The 30% federal solar tax credit (ITC)
The federal Residential Clean Energy Credit returns 30% of your total system cost (solar and battery) as a credit on your federal taxes when you own the system. On a typical $20,000 to $28,000 San Diego installation that is roughly $6,000 to $8,400 back. The credit is set to stay at 30% through 2032 before it steps down, so owning sooner locks in the full amount.
SGIP: California's home battery rebate
The Self-Generation Incentive Program (SGIP) pays a rebate toward home battery storage such as the Tesla Powerwall or Enphase IQ Battery. Every SDG&E customer qualifies for a baseline rebate, and homeowners in a high-fire-threat district or on a medical baseline can qualify for the much larger Equity Resiliency tier. We check your address and utility tier, then handle the SGIP paperwork for you.
NEM 3.0 net billing, and how to beat it
Under NEM 3.0 (net billing), SDG&E credits exported solar at a lower rate than NEM 2.0 did. The fix is storage: bank your midday solar in a battery and use it during expensive evening peak hours instead of exporting it cheaply. Pairing solar with a battery is now the single biggest lever on your San Diego savings.
Rate protection and $0-down financing
Every kilowatt-hour you self-generate is one you do not buy at SDG&E's rising rates, among the highest in the nation. With $0-down financing you can still claim the 30% credit and the SGIP rebate while paying nothing up front, as long as you own the system rather than lease it.
San Diego Solar Incentives FAQ
How much is the federal solar tax credit in 2026?
It is 30% of your total system cost, including battery storage, and stays at 30% through 2032. On a typical $20,000 to $28,000 San Diego system that is about $6,000 to $8,400 credited against your federal taxes when you own the system.
What is SGIP and do I qualify?
SGIP is California's rebate for home battery storage. Every SDG&E customer qualifies for a baseline rebate, and homeowners in high-fire-threat districts or on a medical baseline can qualify for the much larger Equity Resiliency rebate. We confirm your tier before you commit.
Does San Diego still have net metering?
California moved to NEM 3.0 (net billing) in 2023. You still earn credit for exported power, but at a lower rate, so pairing solar with a battery to use your own power in the evening is the best way to maximize value.
Can I combine the tax credit, SGIP, and financing?
Yes. You can claim the 30% federal credit, receive the SGIP battery rebate, and still use $0-down financing, as long as you own the system through a purchase or loan rather than a lease.
The clearest way to go solar in San Diego
Three very different experiences hide behind the same word "solar." Here is how a local, own-your-system installer stacks up against a national brand and a door-to-door lease.
| What matters | San Diego Solar Surfers | National installer | Door-to-door lease / PPA |
|---|---|---|---|
| Who does the work | Local San Diego crew, on your roof since 2013 | Regional subcontractors routed through a call center | Commissioned salesperson; install crew varies |
| You own the system | Yes, you own it and keep every incentive | Usually purchase or loan | No, the company keeps the panels and the tax credit |
| Pricing | Transparent line-item quote, no pressure | National pricing, add-ons at signing | Escalator clauses that raise your rate over time |
| Warranty and service | 25-year equipment warranty, local team answers | Manufacturer warranty, service tickets queued | Tied to a lease contract, not to your home |
| Financing options | $0-down financing, cash, and 30% federal ITC | In-house loan partner | Lease or PPA only, incentives go to them |
| Timeline and control | We handle design, permits, and SDG&E interconnection | Multi-step handoffs between departments | Fast signature, slower follow-through |
The Sunshine Promise
We design your system to a modeled first-year production target and put that estimate in writing before install. If your panels underperform that estimate, our local team comes back, diagnoses it, and makes it right at no charge. That is the Sunshine Promise.
